Polyolefins Journal

Continued increase in global production and consumption of polymeric and petrochemical materials in the last two decades has resulted in vast and widespread academic and industrial research activities, particularly in the field of polyolefins. To cover these advances in research and technology, in a comprehensive and systematic fashion, Iran Polymer and Petrochemical institute, IPPI, has started to launch “Polyolefins Journal”, an international, open access, peer reviewed and multidisciplinary publication on biannual basis in English. The “Polyolefins Journal” accepts original research and review articles as well as reports on major technological breakthroughs in all areas of polyolefins for publication, including: -Olefins synthesis, characterization and applications- Polymerization methods of olefins- Catalysts for polyolefin production- Kinetics and mechanism of polymerization- Characterization and processing- Modeling and simulation- Structure-property relationship- Polyolefins degradation- Other related subjects

Quartiles

The set of journals have been ranked according to their SJR and divided into four equal groups, four quartiles. Q1 (green) comprises the quarter of the journals with the highest values, Q2 (yellow) the second highest values, Q3 (orange) the third highest values and Q4 (red) the lowest values.

Category	Year	Quartile
Catalysis	2020	Q4
Chemistry (miscellaneous)	2020	Q3
Polymers and Plastics	2020	Q3

SJR

The SJR is a size-independent prestige indicator that ranks journals by their 'average prestige per article'. It is based on the idea that 'all citations are not created equal'. SJR is a measure of scientific influence of journals that accounts for both the number of citations received by a journal and the importance or prestige of the journals where such citations come from It measures the scientific influence of the average article in a journal, it expresses how central to the global scientific discussion an average article of the journal is.

Citations per document

This indicator counts the number of citations received by documents from a journal and divides them by the total number of documents published in that journal. The chart shows the evolution of the average number of times documents published in a journal in the past two, three and four years have been cited in the current year. The two years line is equivalent to journal impact factor ™ (Thomson Reuters) metric.

Cites per document	Year	Value
Cites / Doc. (4 years)	2019	0.000

Total Cites

Self-Cites

Evolution of the total number of citations and journal's self-citations received by a journal's published documents during the three previous years.
Journal Self-citation is defined as the number of citation from a journal citing article to articles published by the same journal.

External Cites per Doc

Cites per Doc

Evolution of the number of total citation per document and external citation per document (i.e. journal self-citations removed) received by a journal's published documents during the three previous years. External citations are calculated by subtracting the number of self-citations from the total number of citations received by the journal’s documents.

Cites	Year	Value
External Cites per document	2019	0
External Cites per document	2020	1.143

% International Collaboration

International Collaboration accounts for the articles that have been produced by researchers from several countries. The chart shows the ratio of a journal's documents signed by researchers from more than one country; that is including more than one country address.

Citable documents

Non-citable documents

Not every article in a journal is considered primary research and therefore "citable", this chart shows the ratio of a journal's articles including substantial research (research articles, conference papers and reviews) in three year windows vs. those documents other than research articles, reviews and conference papers.
